How to block a No Caller ID

Calls with “No Caller ID” are generally from telemarketers, hackers, or spammers who are attempting to steal personal information from you. They have disabled their caller IDs on their end to hide their phone numbers, so you won’t be able to file a complaint against them. As a result, some users want to keep their caller ID concealed for privacy and security reasons.
